Muscles of VP
Cleft Palate Exam 1
Term | Definition |
---|---|
What muscle elevates the velum | Levator Veli Palatine |
What muscle is primarily responsible for opening ET, but provides no function in VP closure? | Tensor Veli Palatine |
What muscle is responsible for quickly depressing the velum? | Palatoglossus |
What muscle provides medial movement of lateral pharyngeal walls for closure of velum? | Palatopharyngeous |
What muscle provides the bulk on the nasal surface of velum for tight closure? | Musculus Uvulae |
What muscle provides constriction of lateral pharyngeal walls for tight closure of VP? | Superior Constrictor Muscle |
What muscle assisting raising pharynx/larynx but is not significant in VP closure? | Salpingopharyngeous |
What muscle is the only intrinsic muscle of velum? | Musculus Uvulae |
What is the purpose of the tensor veli palatine for VP? | To relieve stress between hard and soft palate so there is no breakage |
Palatal Aponeurosis | Junction b/t hard and soft palate, formed by tensor insertion |
Is the musculus uvulae on the nasal or oral side? | Nasal surface |
Which muscle creates a bulge on posterior nasal surface of velum? | Musculus Uvulae |
_________ is contained within the anterior facial pillar | Palatoglossus muscle |
Which muscle has both horizontal and vertical fibers? | Palatopharyngeous |
Responsibility of horizontal fibers of palatopharyngeous | Sphincter for lateral and posterior PW, pulls medially |
Responsibility of vertical fibers of palatopharyngeous | Lowers velum, elevated larynx |
_________ is contained within the posterior facial pillar | Palatopharyngeous |
Why are many individuals with clefts hypernasal? | Muscle insertion into bone (hard palate), muscle can't lift bone = velum doesn't elevate to close of VP port, air wastage |
